Description

Control box and display device having the same The present disclosure relates to a control box and a display device equipped with the same. As the information society develops, the demand for display devices is increasing in various forms; in response to this, various display devices such as LCD (Liquid Crystal Display Device), OLED (Organic Light Emitting Diodes), and Micro LED are being researched and used in recent years. Among these, an LCD panel is equipped with a TFT substrate and a color substrate facing each other with a liquid crystal layer in between, and can display an image using light provided from a backlight unit. Additionally, an OLED panel can display an image by depositing a self-emissive organic layer on a substrate having a transparent electrode formed thereon. In particular, a display device equipped with an OLED panel has the advantage of being able to be implemented as an ultra-thin form factor because it does not require a backlight unit. The control box can be spaced apart from the display device and used adjacent to the user. The control box can provide various information to the display device. For example, the control box may be an AV box. The control box can exchange information wirelessly or via wired connection with a display head equipped with a display panel that displays images. Recently, much research has been conducted on the connectivity between such control boxes and display devices. FIGS. 1 to 14 are drawings illustrating examples of a control box and a display device equipped therewith according to embodiments of the present disclosure. Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. Identical or similar components regardless of drawing symbols are given the same reference number, and redundant descriptions thereof will be omitted. The suffixes "module" and "part" used for components in the following description are assigned or used interchangeably solely for the ease of drafting the specification, and do not inherently possess distinct meanings or roles. In addition, when describing the embodiments disclosed in this specification, if it is determined that a detailed description of related prior art may obscure the essence of the embodiments disclosed in this specification, such detailed description is omitted. Furthermore, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and technical scope of the present invention. Terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. On the other hand, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between.
